Creating One Pot Smoked Sausage Pasta is a breeze with these simple steps:

1. Prepare Ingredients: Gather all your ingredients, chopping the onion, pepper, and garlic for easy access.
2. Cook Sausage: In a large pot or Dutch oven, over medium heat, add the sliced smoked sausage. Cook until browned, about 5 minutes.
3. Sauté Vegetables: Add the chopped onion and bell pepper to the pot. Sauté for another 3-4 minutes until softened. Stir in the minced garlic and cook for an additional minute until fragrant.
4. Add Broth and Tomatoes: Pour in the chicken broth and diced tomatoes with their juices.
5. Add Pasta and Seasoning: Stir in the penne pasta, Italian seasoning, red pepper flakes (if desired), and a pinch of salt and pepper.
6. Bring to a Boil: Bring the mixture to a boil, then reduce the heat to low. Simmer uncovered for 12-15 minutes, stirring occasionally, until the pasta is cooked and most of the liquid is absorbed.
7. Add Cheese: Once the pasta is cooked to your liking, stir in the shredded cheese until melted and everything is well combined.
8. Garnish: Remove from heat and let it sit for a few minutes. Garnish with fresh parsley if desired.
9. Serve: Spoon the pasta onto plates or into bowls, and enjoy!
